320990 divided by 72 
Our goal is to divide 320990 by 72.

Advancing to step 1:
3 divided by 72 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 72

Going ahead to step 2:
72 can be fit into 32 0 times, resulting in a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 72

Moving on to step 3:
When dividing 320 by 72, we get 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 288 from 320 to get 32.
Grab the next digit (9) from the dividend, add it to 32, then carry on: 329 / 72

Let's proceed to step 4:
329 divided by 72 is 4 with a remainder of 41.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Deduct 288 from 329 and we're left with 41.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 72

Going ahead to step 5:
419 divided by 72 is 5 with a remainder of 59.
The next digit of our result is 5. 
Result so far: 445.0
The remainder is 59 after subtracting 360 from 419.
Take the next digit (0) from the dividend and append it to 59, then repeat: 590 / 72

Step 6:
72 can be fit into 590 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 4458.0
If we subtract 576 from 590, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 72 is 1 with a remainder of 68.
Use 1 as the next digit of our solution. 
Result so far: 4458.1
Deduct 72 from 140 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
680 divided by 72 is 9 with a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 4458.19
Subtract 648 from 680 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
72 goes into 320 4 times with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 4458.194
Deduct 288 from 320 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
72 can be fit into 320 4 times, resulting in a remainder of 32.
The next digit of our result is 4. 
Result so far: 4458.1944
If we take 288 away from 320, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 4458.1944 with a balance of 0.00032.
